Preparing forcing data: Convert ERA5 pressure levels data to model levels with hybrid coordinate
</p>
<p>
Dear all,
</p>
<p>
I am downscaling ERA5 reanalysis to a higher resolution by using the CCLM regional climate model for the latest month (August. 2023- ). Since only pressure vertical coordinates from ERA5 are available for the latest month (the model levels data with hybrid coordinates are usually three months delayed), I need to convert the pressure level data to hybrid coordinates, which is required for driving CCLM.
</p>
<p>
Does anyone know how to do it? Do I need to consider the topography when we make the conversion? Furthermore, I noticed that there is a function pres2hybrid from NCL (

</a>
), maybe it works? (not sure, I am trying ...)
</p>
<p>
Any help on this matter will be highly appreciated.

<p>
Best regards,
